Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seat, and in particular to a seat cushion for a seat.

In particular, seat cushions that are used for cars, etc., generally have a concave depression in the center of the seat cushion to maintain a stable posture for the person sitting on the seat and to provide a comfortable and luxurious feel. Part or formation, spread out.

Conventionally, the configuration of this unique seat cushion was such that a surface layer material was covered and bonded to a band of foamed urethane molded material that constituted the cushion part. However, the connection was made by crotching the wire to the band and connecting it to the wire through a hanging bag or latch of the surface material, so that the surface material was stretched over the band. . To explain this composition in songs 1 and 2, A shows the entire seat cushion, B shows the recessed part, and ■ shows the front with the hanging bag. It is a material. 2. At Gundo,
Reference numeral 8 indicates a tL wire embedded in the hand 2, and reference numeral 4 indicates a number of latches for connecting the wire 8 and the hanging bag 1a.

In a seat cushion having such a structure, the wires, latches, etc. are subject to the pressure of the body nails of the seated person, and the seated person has the disadvantage that the seated person feels an unpleasant foreign body sensation as a reaction.

In addition, the number of man-hours required to manufacture 4p+J was large, and the disadvantage was that the 2-stroke was high.

In order to completely reduce such defects, there are also sheets that have been improved as shown in FIGS. 8 to 4. That is, 5
is a skin made of material that can be welded by high-frequency heating; 6 is a urethane material wadi/g; 7 is a foamed urethane material band;
8 is made up of the back base fabric Kanakin, etc. And this M1 vehicle 5 parts are subjected to high frequency welder upper and lower part 9,
9, applying pressure at t1 and melting and bonding the surface material and the band 7 as shown in Fig. 41 using a frequency heating melting machine.
It has been completed. However, even in this type, the connection of the 1g bonding parts 5a, 5b, 5e, etc. is not perfect, and after long-term use, it loses its resistance to vibration, frictional contact, etc., and the base material There was a durability problem in that the part of the urethane material in the barrel was torn and separated.

The present invention is intended to eliminate the above-mentioned defects in conventional seat cushions. In other words, the band is equipped with a belt member that can be welded by high frequency, or a part of the belt to be welded. The band is buried within the band in such a manner that only the band is completely exposed.

Then, a surface layer material capable of high frequency welding is fused at a predetermined welding location on the band by high frequency welding means.

Therefore, in the seat cushion of the present invention, the bond between the surface layer material and the band is strong, and since the mesh is buried in the band in areas other than the exposed area, the mesh is strongly filled with G1 matrix urethane, There is no color sequence that would cause the base material to be torn off and peeled off.

The opening is large and helps improve durability.In addition, no metal fittings are required to connect the band to the surface material.
It is comfortable to use and easy to work with.

Next, embodiments of the present invention will be described with reference to the accompanying drawings.

In Fig. 5, 10 is a band made of urethane foam material;
1 is capable of high frequency welding (for example, nylon).

It is a net fabric made of polyester, vinyl chloride, etc.). The net member 111 is stretched between one frame member lla (
On the other hand, predetermined portions 11b and 11 (not shown) are embedded in the band 1() and are welded to the surface layer material.
l c , 11. The d portion of the band is exposed in the table 11f] and the size is 1-z.

In addition, when welding 10n, lob, etc., high frequency welder σ electric current (・, accept the tt6, pad position 1c, and groove to prevent base metal deformation τ1<) are applied. mosquito,
A detailed description in OJ, which is not the gist of the present invention, will be omitted.

In producing the wood R01,j sheet, the surface layer of paulownia is positioned and arranged on the above-mentioned net part 11 or the buried ttl pad 10 as seen in the 6th FA.

On the other hand, the surface material in the case shown in the wood example has a high frequency of 1 no.
It is composed of an outer skin 12 made of a material that can be heat-welded (for example, nylon, polyester, J4 vinyl, etc.), a wadding 18 made of urethane material, and a back base fabric 14.

(Although it is preferable that the backing fabric 14 is made of a material that can be welded by high frequency welding, it is not necessarily limited to this, and depending on the situation, the backing fabric itself may not be used.) Then, the band is Fit the electrode part 158 of the welding welder 15, and press B2 with the high frequency ugly welder upper and lower molds 15 at 15 degrees together with the positioned and determined surface layer material.
As shown in FIG. 7 and shown in FIG. 8, a fusion-bonded product of the band and the surface layer material is completed.

Fig. 9 shows a different σ] real example, in which the electrode part 15a' of the welder type 15° is welded by the related frequency wave.
1. A tape 16 made of a curved material for frequency heating welding was held, and 116 pieces of g-data were also melt-bonded to the skin 12 in the same period. (See Figure 10) This tape 16
The simultaneous welding of the two can enhance the bonding strength between the six ends and the surface material, and can also provide an elegant appearance. (FIG. 11) It is preferable that the surface layer material be a material capable of high frequency welding, but it is not necessarily limited to this material. Furthermore, the tape itself is not limited to a sheet shape, and by appropriately setting the shape of the electrode portion to be held, it is also possible to hold and melt a tape with a three-dimensional cross-sectional shape, and its arrangement.
